Crystal Meth is the street name for the drug Methamphetamine, the effects of which are increased alertness, energy, concentration, and in high doses can induce euphoria, increased libido, and enhanced self esteem. The risk of addiction is very high as the drug releases dopamine in the brain that causes all the above. Another name is Desoxyn which is a trademark name and is dispensed in the USA for the treatment of ADHD.
There are many physical effects Methamphetamine can cause including hyperactivity, dilated pupils, anorexia, restlessness, dry mouth, headaches, flushing, hypotension, hyperthermia, diarrhoea, constipation, dizziness, blurred vision, insomnia, twitching, itchy skin, acne, and in high doses convolutions, heart attacks, strokes and death.
The withdrawal symptoms experienced from Methamphetamine include depression, fatigue, increased appetite, anxiety, headaches, irritability, excessive sleeping (hypersomnia), vivid or lucid dreams and suicidal thoughts. Long term use may cause ongoing depression, serious heart disease, anxiety and violent behaviours and suicide. Methamphetamine is neurotoxic and in long term use can increase the risk for Parkinson’s disease or a long-lasting psychosis similar to schizophrenia. Methamphetimine users may lose their teeth very quickly informally known as meth mouth. Meth mouth is a combination of drug induced psychological and physiological changes resulting in xerostomia (dry mouth), frequent consumption of high calorie, carbonated beverages and teeth grinding.
Methamphetamine is a highly addictive drug and the recovery process is difficult and relapse is often common as the drug induces hyper-stimulation and when no longer in the system the onset of depression is common.
